MARTIN W. POND AND LYMAN W. DARLING, OF ELYRIA, OHIO.

HARNESS BREAST-STRAP SLIDE.

Specication forming part of Letters Patent No. 41,320, dated January 19,1864.

To aZZ whom, t may concern:

Be it known that we, MARTIN W. POND and LYMAN W. DARLING, of Elyria, inthe county of Lorain and State of Ohio, have invented a ne W and usefulmode of protecting the breaststraps of teamharnesses from the chatingwear of thc neck-yoke rings; and we do hereby declare that the followingis a full and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,in whichrlhe figure represents a perspective view.

The nature of our invention consists in providing the ordinarybreast-strap of team-harness with a metallic shield secured to 'asnitable leather loop, which slides over the breaststrap and supportsthe rings ofthe neck-yoke and protects the strap from chan g andwearing. It also allows the pole of a wagon to vibrate more freely thanit otherwise would, thus preventing' any undue wrenching or suddenjerking of the horses.

'lo enable others skilled in the art to make and use our invention, wewill proceed to de` scribe its construction and operation.

A represents a concavo-convex metallic plate, which is secured firmly tocurved leather loop B, through which the breaststrap passes. a a aresmall, stout, curved, conically-formed projections, which start out fromtheir base and project in an oblique direction on a curve toward theopposite side of the plate A, slightly passing its center, as seen inthe drawings. The lines of their divergence, being parallel, are such aswill freely admit the ring of the neck-yoke when turned to the properangle of Obliquity. After passing below the ends of the projections itnaturally assumes a position at right angles to the shieldplate. Theinside curve of the projections are such that, in connection with thecurve of the baseplate, it forms an oval, the extremities of which areimmediately at the base of the projections, and forms a secure seatwherein the ring is held in case the plate is tilted toward either end,thus effectually (in combination with flanges c c) preventing the shieldfrom being turned over or upside down, as would be the case without thisdevice.

The advantages of this device are too obvious to need comment.

What we claim as new, and desire to secure by Letters Patent, is

The metallic shield having its curved diverging projections, and beingsecured firmly to a suitable loop of leather for the purpose ofprotecting the breast-strap of harnesses from the chating and cutting ofthe rings of the neckfyoke, the whole being constructed and arranged inthe manner substantially as set forth.
